BASF’s latest PIN flame retardant PPA grades provide thermal stability, high electrical insulation and low water uptake. The PIN FR polyphthalamide (PPA) range includes compounds based on PA9T, PA66/6T, PA6T/66 and PA6T/6. These offer ease of processing, electrical RTI up to 160°C. The absence of halogens to EN 50642 avoids corrosion and possible failure of electrical systems. PIN flame retardants ensure UL 94 V-0 down to 0.4 mm, as per cable management standard CMS EN 50654 (2018-5). Low water uptake and resilience of mechanical and electrical properties (dielectrical strength) at high temperatures ensure reliability with ageing and suitability for e.g. consumer electronics, transport applications, electric vehicles, miniature circuit-breakers, wire-board and board-board connectors, switch gear and sensors. BASF offer a total of over 50 compound grades of PPA for injection molding and extrusion.
